IMPROVEMENT IN HAY AND GRAIN UNLOADERS.

Specification forming part of Letters Patent N 0. 198,574, dated December 25, 1877; application filed December 4, 1877.

To all whom it may concern: Beit known thatLBoBERtr O0WDEN,.of r j New Richmond, in the county of Crawford 1 and State of Pennsylvania, have inventeda 0 new. and useful Improvement in Apparatus for Unloading Hay and Grain, of which the following is a speeificationz' v Figure 1 is a vertical longitudinal section of my improved apparatus, taken through the line .70 as, Fig. 2. Fig. 2 is atop view of the U vsame. Fig. 3 is a side view of the hoistingblock and its attachments. A v Similar letters of reference indicate corresponding parts. I r y r The object of this invention is to-furnish an I improved apparatus for unloading hay and o it grain, which shall be so constructed as to enable the hay and grain to be unloaded quickly and conveniently andwithout being scattered and wasted. V l o The invention consists in the combination of the hinged frames and their hooks with-the rack, to divide the load into sections; in the combination of the bars and ropes with the r rack and the hinged frames; and in the combination of the block,providedwith the loop, 113116 pulleys, the hook and eye, and the two ropes, with the hoisting-rope and the ropes and bars, as hereinafter fully described.

, A represents an ordinaryhay-rack, which (is placed upon awagon in the usual way. To the front end of the rack A is attached a cross-frame, B. To the side bars of the rack l A are hinged, at equal distances apart, three (more or less) cross-frames, G, which are held erect by: hooks 1), pivoted; to the rack A, and ---"hookinfg into eyes orstaples attached to the lpostsof the .said frames 0. The frames 0 .thus divide the load into equal and distinct v sections, each of which i may be removed without disturbing the others. 1 z V fi E are two,bars,hinged toieaoh other atzone end, and which are made of such a length'as Ito reach across, or nearlyacross, the rackA, To. the outer and inner endsiofthe bars Ecaref. attached the inner ends ofi three pairs of? ropes, j The'outerendsofthe'three ropesEupon "G. The-ropes. F arejmade of such a length".

"c", attached to the centers of, the top bars of jgkthe frames (3; Thel sectionslof the load are v built upon the bars and ropes E F, between 5' he nam s 0, and a1? 1 e i distiller? that the rings G maybe hooked upon fpins V H is a block, to the top of which is attached a loop or eye, M, to receive the hook of the hoisting-rope I. To the lower side of the block H are pivoted a hook, J, and eye K. To the eye K are attached the ends of two ropes, L M, which pass over guide-pulleys h, pivoted to the opposite edges of the bottom of the block H, or to short arms attached to said block.

The ropes L M extend down into such a position that they may be reached by the operator, the one, L, being designed to hold the eye K upon the hook J and the other, M, to draw the said eye K off the said hook J, when the load has been carried to the place where it is to be dropped. The hoistingrope I is passed over pulleys, and is drawn by a horse in the same manner as when a fork is used for unloading. When the loaded wagon has been drawn to the barn or other place of unloading, the hoisting-rope I is unhooked from the block H, passed through one of the rings Gr, and again hooked into its loop. The other ring G is then passed over the hook J, and the eye K is passed over the end of the said hook, and the section of the load is ready to be raised. By this arrangement, when the rope M is pulled to drop the load the ropes and bars F E will remain suspended from the block H by one of the rings G, and will be brought back to the wagon by and with the said block H. I

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the hinged frames 0 and. their hooks D with the rack A B, to divide the load into sections, substantially as herein shown and described.

2. The combination of the bars E and ropes F with the rack A B and the hinged frames G, substantially as herein shown and described.

3. The combination of the block H, provided with the loop h, the pulleys 12?, the hook and eye J K, and the ropes L M, with the hoisting-rope I and the ropes and bars F E, sub- 'fstantially as herein shown and described. each. side meet," and are-attached to rings r ROBERT oowDEN.
